The valve stem heart of the eccentric butterfly valve deviates from the center of the disc and the center of the disc, and the butterfly valve with the seal is called the eccentric butterfly valve.The eccentric butterfly valve and the upper and lower valve shaft adopt a link method of a different holes and a shaft. During the opening and closing of the butterfly board, the unprecedented link of the butterfly board floating, left and right, and reducing the interference area between the butterfly board and the valve seat., Thus greatly reduced the torque.
Eccentric butterfly valve installation direction
1. A offset formed by the center of the valve shaft and the valve board. 2. A offset formed by the center line of the valve axis and the center line of the valve body 3.
